i To all whom t may concern:

Be it known that I, FRANCIS W. CARPEN-` TER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Feeder Attachments for Threshing-Machines, of which the following is a specification.

My invention relates to improvements in wing carrier attachments for threshing machines.

Among the objects of the invention are to provide an attachment having lateral wing troughs` which attachment is adapted to be universally mounted upon threshing machines of present standard makes, and also to be easily attached thereto and detached therefrom.

The attachment is designed to support heavy troughs in a position free from the ground, and so that the troughs shall be capable of a wide range of adjustment upon the supporting part of such attachment.

To this end the attachment preferably consists of Wing troughs with driving and supporting connections therefor supported upon the free ends of boom structures, means connecting the inner ends of the boom structures to the threshing machines so as to hold them in rigid relation therewith, and means for supporting the boom structures rigidly enough to overcome the strains and stresses caused particularly by the weight of the troughs and driving supports on the free ends of the boom structures, the attachment as a whole being adapted for support in connection with different types of feeders.

In an attachment ofthe class described in which very heavy troughs with driving and supporting connections are supported upon the free. ends of the boom structures, and which is adapted for attachment to threshing machines of varying widths and heights of feeders, certain fundamental diiiiculties must be overcome, and this is accomplished by the particularly novel combinations covered in the claims.

My invention is an attachment adapted to be assembled at the factory for application to threshing machines containing feeders of different widths and heights, and then taken to the iield and attached to the machine.

The attachment as a whole, including the troughs, embodies features whereby the boom structures, when attached, are held in rigid relation to the machine, and the driving supports of the troughs are supported s'o as to'resist the exceptional strains and twists caused by the swinging of the heavy wing troughs upon the free ends of the long boom arms. A particular advantage is obtainable by the members common to the boom structures joining them and holding them in rigid relation and serving as a means of attachment to the front end of the threshing machine.

My attachment is essentially distinguished from those construct-ions in which feeder troughs are so supported as to form an integral structure with some particular type of feeder, and from those constructions in which l,the outer ends of the troughs rest upon the ground, and which, therefore, do not need the features and combination of elements necessary in the universally-adaptable attachment of the class described.

The invention consists further in the features of construction and combination of parts hereinafter particularly described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the accompanying drawings forming part of this specification, Figure l is a side elevation of the front end of a threshing machine shown fitted with my invention. Fig. 2 is a front elevation of the same. Figs. 3, l and 5 are detail views of supports for the conveyor. Fig. 6 is a perspective view of one of the conveycr troughs. Fig. 47 is a diagrammatic front elevation of the machine. Figs. 8 and 9 are detail views of adjusting rods forming part of the invention. Figs. l0 and l1 are end and fragmentary side views, respectively, of one of the conveyer troughs.

Referring to the drawings, A represents an ordinary threshing machine.

C represents an attachment frame which may be secured to the thresher in any suitable manner, as by means of bolts 2. The attachment frame consists essentially of a horizontal bar 3 through which the bolts 2 pass, and uprights L slidably supported on the ends of the bar by means of couplings 5. The upper ends of the uprights A are ad* justably connected by a horizontal bar 6, which bar, as shown in Fig. 7, projects some distance beyond the side bars to form rests for the conveyors B when in the position shown in Fig. 1. Slidably supported upon the vertical bars 4 by means of sleeves 7, are horizontal arms or booms 8 slidably connected at their outer ends with extension arms 9 supporting elbows 10. The extension bars 9 have adjustable connection 11 with the sleeves 7. Rotatable upon the upwardly-extending portion of each elbow 10 is a yoke 12 forming a journal support for the inner end of the adjacent trough 14. A horizontal shaft 13 is j ournaled in the inner end' of each conveyer trough, as shown in Fig. 3, and carries atone end a bevel pinion 15 which intermeshes with a similar pinion 16 upon an upright shaft 17. rlhe lower end of this shaft has a bevel pinion connection 18 with a horizontal shaft 19, which, in turn, carries a sprocket-wheel 2O which is connected by a chain 21 with the driving mechanism. Secured upon the horizontal shaft 13 is a sprocket-wheel 22 connected by aI conveyer chain 23 with a sprocket-wheel 24 in the outer end of the -conveyertrough.

The conveyer chain 23 preferably runs with-` in a channel bar guide 25, the inner end of the guide 25 being formed with projecting flanges 26 t0 force the material away from the teeth of the chain. The booms 8, eX- tension arms 9, sleeves 7, connections 11 and uprights 4, constitute boom structures, and upon the free end. of each of these boom structures is supported the associated trough 14.

In order to swing the conveyers in horizontal planes I provide rods 27 each of which has a pivotal connection 28 with one side of its associated trough, each of the rods 27 being slidable through a block 30 having pivotal support, as shown in Fig. 6, on the bar 6, the rods 27 being held in adjusted positions in the blocks 3() by means of pins 29.

To swing the troughs in vertical planes I provide for each of the same a. windlass 31 preferably supported upon the feeder and connected with the conveyer troughs by means of cables 32 running over idler pulleys 33 carried by a frame 34. The ends of the cables 32 are connected with bails 35,

which bails have pivotal connection 36 with.

the sides of the troughs, as indicated in Figs. 10 and 11. The frame 34 has pivotal support 37 upon the feeder so as to swing toward and away from the fra-me which is constituted by the bar 3, the uprights 4, and the horizontal ba-r 6, and is connected to such bar 6 by adjustable bars 38.

That the frame which is made up of the bar 3, the uprights 4, and the bar 6 may be readily held after its application to the threshing machine, brace. rods 39 are employed, said rods being connected to the bar 6, and anchored on the body of the machine A. The brace rods 39 impart rigidity to the frame, and serve to hold the latter in position to resist-the strains and stresses imposed thereon incidentl to the weight of the wing conveyers B, and the material which the same convey. Y

Itwill be seen that the attaclnnent is independent of the particular construction of threshing machine or feeder, and may be attached to or detached from machines embodying different styles of feeders without changing or affecting the construct-ion of the feeder or machine.

The cross-bar 3 and couplings 5 constitute members joining the boom structures and holding them in rigid relation, and serve as a means of attachment to the front end of the threshing machine, and the crossbar 6 in connection with the brace rods 39 and connected parts form means cooperative with said attachment parts to hold said boom structures in rigid supporting position to resist the strains and stresses imparted to the free ends of the boom structures by Jtheir suspended wing troughs, These fe:- tures constitute an important part of the invention to accomplish the results desired, and may be structurally modified without departing from the idea of my invention.

In applying the invention to a threshing machine, the trough supporting framework having been adjusted to tit the particular type of feeder, drivingchains of proper lengths will be fitted thereto, thus putting the apparatus in condition for operation wit-hout any further adjustments. A

f It will be further evident that I secure by means of my improved features of invention a construction which may be removably supported in connection with the feeder of a threshing machine and adjusted to fit varying sizes of feeder. After being set up and adjusted to the feeder the endless chains will be driven through the medium of the gears 2O which, as stated, may be properly connected with the driving mechanism of the machine and need not be adjusted after the mechanism is set up.
